Samenvatting

High resolution 13C n.m.r. spectra of solid ethylene-vinyl alcohol (EVOH) copolymers have been observed, exhibiting a splitting of the methine carbon resonance. This splitting could be explained taking into account a rather unique combination of both tacticity effects and sequence effects. An explanation is offered for the values of the 13C n.m.r. chemical shifts which is based on substituent induced shifts taken from rigid compounds rather than hydrogen bonding
